Makibako is a female racehorse and the younger sister of Midori Makibao, the main protagonist of the series. She belongs to a prestigious bloodline, being the daughter of Sunday Sidance and Midoriko, which makes her the half-sister of Makibao. In Dokodemo Makibao ~World Tour~, she joins her brother and his companions on a global racing tour, serving as a new member of the group and adding a fresh dynamic to their chaotic adventures. Her personality is characterized by a spirited, energetic, and competitive nature. She is strong-willed and determined, often displaying a lively and confident attitude that matches her brother's own tenacity. Her motivations include supporting Makibao in his quest to defeat his rival Cascade, as well as proving her own abilities as a racehorse on the world stage. She participates in the series' absurd and location-themed races, using her natural speed and inherited racing talent to contribute to the team's efforts. Her key relationships are primarily with her brother Makibao, whom she looks up to and travels alongside from the start of the season, as well as with the other recurring characters such as Chūbee and Kansuke, with whom she shares comedic and supportive interactions. While her development is limited due to the short-episode format, her presence strengthens the group's cohesion and brings an additional layer of energy to the story. Her notable ability lies in her racing skill, which is implied to be considerable given her distinguished lineage.
